Conventionally, this type of packaging was continuously sealed.
For example, the configuration disclosed in Japanese Utility Model Publication No. 53-32869 is well known. In this well-known sealed package, both the vertical seal and the horizontal seal are twill-shaped seals,
Both of these seals are continuously formed by a pair of seal rolls. [Problem to be Solved by the Invention 1] In the conventional example described above, the sealing method is to sandwich the folded film sheet from both sides by a pair of seal rolls, heat melt it, and weld it together to seal it. It is. In order to form a twilled seal, the seal roll used has a jagged chevron-shaped surface, and these chevrons match with high dimensional accuracy between the pair of seal rolls, and this is achieved by applying a predetermined pressing force. If it is not pressed, it will not be possible to obtain a sealed package consisting of an accurate and reliable seal. However, when the above-mentioned sealed package is made of 7 bags, the chevron-shaped burrs (unevenness) of the twilled seal part are particularly minute, so the sealing work is carried out continuously at a considerable speed. It is extremely difficult to visually determine whether the unevenness of the sealing part is accurate or not under the condition that the sealing part is in a state where it is difficult to visually determine whether the unevenness of the sealing part is accurate or not. The seal pressure of both seal rolls had to be adjusted by inspecting the package. Therefore, while this adjustment is being carried out, the drive of the machine must be stopped, resulting in a problem in that the production efficiency is significantly reduced. [Means for Solving the Problems 1] As a specific means for solving the problems of the conventional example, the present invention provides a method of supplying a laminated film sheet by folding it in half, and making the overlapping ends of the film sheet long.

In a packaging device equipped with a seal roll that continuously seals 1J vertically and horizontally seals each sealed package,
The seal roll that performs the vertical sealing is provided with a predetermined 11 lattice-like uneven seal portion forming surfaces and a solid seal portion forming surface of a predetermined width, and the solid seal portion forming surfaces are provided with raised protrusions that allow visual confirmation of changes in the strength and weakness of the sealing pressure. A continuous sealing device for a dense package formed of a laminated film characterized by having grooves formed continuously in the vertical direction is provided, and by forming the raised protrusions, During packaging work, changes in the sealing pressure of the sealing roll can be easily observed with light, making it possible to quickly change the strength or weakness of the sealing pressure of the sealing roll even during packaging work. It can be adjusted reliably. [Example 1] Next, the present invention will be explained in detail with reference to the embodiment shown in Figs. A non-low-temperature-fusible film 3 such as nylon or aluminum foil is laminated on the top surface of a plastic film 2, and is folded in half with the non-low-temperature-fusible film 3 on the outside. Reference numeral 4 denotes a guide that continuously forms the film sheet 1 into a cylindrical shape, and is attached to a desired position on a grip body (not shown). 5.5 is the longitudinal direction of the film sheet 1 formed into a cylindrical shape by the guide 4! A pair of vertical sealing rolls are provided with a heat sealing part 5a that forms a cylindrical bag body a by forming a vertical sealing part 6 at the F joint edge. 7.
A pair of horizontal sealing rolls 7 are located below the vertical sealing rolls 5.5 and are attached to the machine body, and are heated horizontally across the vertical sealing portion 6 of the film sheet 1 at right angles. A lateral heat sealing portion 7a is provided for sealing. Reference numeral 8 denotes a horizontal seal portion formed by the horizontal heat seal portion 7a. Reference numeral 9 denotes a supply means for filling and supplying the contents, and although a nozzle is shown in this embodiment, the present invention is not limited to this. 10.10 is a gear for rotationally driving the vertical seal roll 5.5; 11.
11 is a tooth width for rotationally driving the horizontal seal roll 7.7, and these tooth widths 10.11 are the tooth widths 10 and 11 of the seal roll shaft 10a.
, 11a, and are configured to be rotated synchronously at a rotational speed of 1:1. 12.
Reference numeral 12 denotes a roll cutter, which cuts the horizontal seal portion 8 in the horizontal direction from its center. b is the completed dense 11 package as shown in the third figure. Such a film sheet 1 is continuously fed, and is sandwiched from both sides by a pair of vertical seal rolls 5.5 and a pair of horizontal seal rolls 5.
and a horizontal seal portion 8 are applied. In this case, the vertical seal portion 6 is formed of a lattice-like uneven seal portion 6a and a solid seal portion 6b in parallel, and furthermore, vertical raised protrusions 6C are continuously formed on the solid seal portion 6b. Note that the horizontal seal portion 8 is formed halfway to leave a filling space 13 for the contents, and is a solid seal portion, but there is no problem in forming it as a lattice-shaped uneven seal portion. As shown in FIG.
The seal part forming surface 14 with the lattice-shaped unevenness for forming the lattice-shaped uneven seal part 6a on the right and the solid seal part forming surface 15 forming the solid seal part 6b are on the right, and this solid seal part forming surface A vortex 16 for forming the raised convex strip 6C is formed on the ridge 15. [Description of Operation 1] The actual sealing operation, which is the main part of the present invention, will be explained using the above-mentioned vertical sealing roll 5.5 and horizontal sealing roll 7.7. The film sheet 1 is fed using the conventional two-fold feeding device or means, with the vertical sealing roll 5.5 continuously sealing the vertical sealing portion 6, and the horizontal sealing roll 7.7 performing the horizontal sealing. Part 8
is performed intermittently. In this vertical seal portion 6, as described above, the lattice-like uneven seal portion 6a and the solid seal portion 6b of a predetermined width are continuously formed. is heated from both sides to melt the low-temperature melting film 2 located on the inside, and is pressed to form an adhesive 1J.
Due to the suppression, the inner low-temperature melting film 2 is sequentially melted and the excess is pushed out.
Since the excess is pushed into the raised ridges 6C formed in the ridges and absorbed as a whole, the strain on the seal part is eliminated, and the seal base (content filling space 13 The entire seal is extremely strong, with no damage to the surrounding area, no pinholes, and no wrinkles or folds that reduce commercial value. In addition, by forming the outer edge of the vertical seal portion 6 in the form of a thin lattice-like concavo-convex seal portion 6a, the sealed package can be easily torn. Furthermore, when the vertical seal portion 6 consisting of the lattice-shaped uneven seal portion 6a and the solid seal portion 6b is continuously formed, the raised ridges are formed by forming the raised ridges 6C continuous in the vertical direction on the solid seal portion 6b. By visual inspection, it is possible to immediately detect changes in the seal pressure of the seal roll to determine whether the 6C is formed in the correct shape. In other words, the formation of the raised protrusions 6C in the vertical seal portion 6 that is continuously formed has a certain shape and form (protrusion dimension, []11 dimension) in advance. .5 is determined based on the seal roll pressure, heating temperature, and 4471 of the film, and as the raised protrusions 6C are continuously formed in the vertical direction, the set shape and form are formed. This can be detected directly by visually checking C). If the shape or form is out of shape, it is only necessary to make fine adjustments during the packaging process without stopping the drive of the device so that the set shape or form is achieved. In the illustrated embodiment, the raised convex stripes 6C are formed on both sides, but the same effect can be achieved even if they are formed on one side.Also, instead of visual inspection, a sensor or the like is placed on the raised convex strips forming portion. It is also possible to determine the shape and form of the raised protrusions by setting them. [Efficacy of invention! ! 1 As explained above, the continuous sealing method for a sealed package formed of a laminated film according to the present invention involves feeding a laminated film sheet by folding it in half, and folding the overlapping ends of the film sheet in the longitudinal direction. In a method in which the outer edge is vertically sealed to a predetermined lattice-shaped uneven seal part of the inside of A9 and the inner edge is continuously sealed to a solid seal part of a predetermined rlJ along the longitudinal direction, and horizontally sealed for each sealed package. ,
Since the solid seal part is formed with continuous raised protrusions in the vertical direction that allow visual confirmation of changes in sealing pressure between strong and weak levels, the raised protrusions allow the sealing pressure of the seal part to be controlled even during packaging operations. It has the excellent effect of being able to read strong and weak changes immediately, stop the drive of the device, and easily adjust the sealing pressure without having to worry about it, allowing work to be carried out with high efficiency without reducing productivity. Further, the sealing device of the present invention feeds a laminated film sheet by folding it in half, and seals the overlapped ends of the film sheets along the length direction with a thin lattice-shaped concavo-convex seal having a predetermined width on the outer edge. In a packaging device equipped with a seal roll that vertically seals the inner edge continuously in a predetermined solid seal part of "[" in the section] and horizontally seals each of the 14 packages, the seal roll that performs the vertical seal has a predetermined In order to provide a lattice-shaped uneven seal part forming surface of 111 and a solid seal part forming surface of a predetermined +lj, and to form continuous raised protrusions in the vertical direction on the solid seal part forming surface so that changes in the strength and weakness of the sealing pressure can be visually observed. Because of the structure in which grooves are provided, vertical seals can be formed in two types, a lattice-like uneven seal part and a solid seal part, and the raised protrusions are formed in the vertical direction on the solid seal part, and the raised protrusions are It also serves as reinforcement for the seal part and at the same time increases the seal pressure.
It also serves as a guide for weak changes, and in order to form the raised protrusions into an appropriate shape and form, even during the beginning of operation at 6g, the sealing pressure should be adjusted to reflect strong and weak changes in the above raised protrusions. The effect is that you can adjust the inside of the cylinder while visually checking the oscillation.
